Digital signal processing circuit has resistors individually connected to inverting input terminal, non-inverting input terminal and output of differential amplifier

摘要

A resistor (R1) is connected between an input terminal (E) and the non-inverting input terminal of a differential amplifier (V1). The resistor (R3) is connected between the output of the differential amplifier and the parallel connection of a shunt capacitor (C2) and the resistor (R2). The resistor (R4) is connected between the input terminal and the inverting input terminal of the amplifier.
